About Thoma Electric

Right around 1961, Clarence Thoma, a.k.a. “Bud,” founded Thoma Electric. Originally a contracting business, Bud and his staff performed electrical construction for some of the Central Coast’s most notable landmarks. From the first branch of Mid-State Bank, to rewiring the popcorn popper at San Luis Variety, Thoma Electric has made its lasting mark on the Central Coast region for over 50 years.

Thoma Family

In 1981, Thoma Electric expanded service into electrical consulting, engineering and design. Since that time Thoma Electric has grown dramatically throughout California and the West Coast, providing consulting, engineering, design and construction services for some of the region’s most prominent projects through innovative ideas and environmentally sustainable principles applied to every project they work on.

Fifty + years of electrical engineering and construction have established an unwavering commitment to quality in all phases of our work. Our primary mission is to:

  • Maintain the highest level of integrity, accountability, and commitment to total customer satisfaction.
  • Recruit the most qualified corps of industry professionals.
  • Lead our industry in promoting energy conservation and environmental sustainability.

  • Uphold these values in every phase of company operation.
